Cage of covariance in calibration modeling: Regressing multiple and strongly correlated response variables onto a low rank subspace of explanatory variables
(Peer reviewed; Journal article, 2021)In analytical chemistry, multivariate calibration is applied when substituting a time-consuming reference measurement (based on e.g. chromatography) with a high-throughput measurement (based on e.g. vibrational spectroscopy). ... -
Distribution based truncation for variable selection in subspace methods for multivariate regression
(Peer reviewed; Journal article, 2013)Analysis of data containing a vast number of features, but only a limited number of informative ones, requires methods that can separate true signal from noise variables. One class of methods attempting this is the sparse ... -
Extension of SO-PLS to multi-way arrays: SO-N-PLS
(Journal article; Peer reviewed, 2017)Multi-way data arrays are becoming more common in several fields of science. For instance, analytical instruments can sometimes collect signals at different modes simultaneously, as e.g. fluorescence and LC/GC-MS. Higher ... -
Multi-block regression based on combinations of orthogonalisation, PLS-regression and canonical correlation analysis
(Peer reviewed; Journal article, 2013) -
Second-order calibration in combination with fluorescence fibre-optic data modelling as a novel approach for monitoring the maturation stage of plums
(Peer reviewed; Journal article, 2020)In this work, non-destructive autofluorescence of plums was employed to study the chlorophylls’ concentration evolution along the maturation process. For that, excitation-emission matrices (EEMs), containing full fluorescence ... -
Variable time delay estimation in continuous industrial processes
(Journal article; Peer reviewed, 2024)Digital sensors and machine learning enable efficiency improvements in production processes, through process monitoring, anomaly detection, soft sensing, and process control. However, the development of such solutions ...
